BASE FCR SUPPORTING SWITCHES AND THE LIKE UP ON OONDUITS.

Application filed October 26, 1905. SerialNo. 284.472.

T aZZ whom it nmq concern:

Be it known that we, CLARENCE C. SIBLEY, residing in Perth Amboy, Middles ex county, New Jersey, and GEORGE A. LUTZ, residing in New Yorlr city, borough of Brooklyn, New York, citizens of the United States, have in vented certain new and useful Improvements in Bases for Supporting Switches and the Like upon Conduits, of which the following is a s ecification.

he object of this invention is to provide improved means to permit the ready mountmg of electrical fittingssuch as switches,rosettes, and analogous fittings-upon or in connection with conduits for electric wires. To this end a base is provided, preferably of insulating material, ada ted to fit upon or over a conduit, and such ase is provided with means to permit the attachment thereto of switches and analogous fittings that may vary in dimensions, whereby to enable such fittin s that may be upon'the market to be readi y mounted upon or used in connection with conduits without requiring the fittings to be separately constructed for use in connection with the conduits, although speciallyconstructed fittings may be mounted upon such bases.

The invention further comprises the novel details of improvement that will be more fully hereinafter set forth and then pointed out in the claims.

Reference is to be had to the accompanyin%drawings, forming part hereof,wherein igure 1 is a plan view illustrating a wellknown type of switch mounted upon the improved base. Fig. 2 is a section on theline 2 2 in Fig. 1. Fig. 3 is a view similar to 1 with the cap ofthe switch removed. Fig.

4 is a plan view of the improved base looking in the direction of the arrows 4 4 in Fig. 2-. Fig. 5 is an inverted plan view of the switch looking in the direction'of the arrows 5 5 in Fig. 2; and Fig. 6 is a side elevation at right angles to Fig. 2; showin the base mounted upon the conduit, parts eing broken away.

Similar numerals of reference indicate corres onding parts in theseveral views.

. he numeral 1 indicates a base which may be of any suitable material, referably of porcelain, and which is provide on its under side with a gain or recess 1, adapted to receive a conduit, as 2, whereby the base may be conveniently fitted upon theconduit, so

that the sidpbrtionsl of the base will be on opposite sides of the conduit.

At 3'i's'ii1dicated -generally a switch; such as a snap-switch any well-known construction, the base or insulating portion 3 of which is adaptedto fit u on the base 1. The upper part or top of ase 1 is shown provided with holes 1, that communicate with I the gain 1 and with the upper surface of the base to permit the wires frond conduit 2 to be drawn through the top portion of the base for connection with electric fittings. In order to permit such wires to be conveniently passed under the base 3* of a fitting for connection with the terminals thereof, the upper surface of base 1 at the sides of the holes 1 is preferably recessed at 1 on one or both sides of the holes 1, the bottoms of which recesses 1 preferably incline upwardl from the ed es of holes 1 to the surface of ase 1, where y the parts of the recesses 1 adjacent the ed es of holes 1 will be the deepest, although t 's particular shape of the recesses 1 may be varied. By this means when the wires are drawn from the conduit 2 through the holes 1 for connection with the terminals of the switch or other fitting 3 the wires may lie convenientlyin the recesses 1 beneath the base 3, whereby the outer rim portion of the getter may fit snugly upon the top surface of ase 1. v

The base 3 of the switch is shown provided with customary holes 3* to receive screws 3 for holding the switch upon a su port, and in the example illustrated in the 8 base 1 is provided with means to receive the screws 3 for holding the switch upon base 1. As the switches or analogous fittings to be mounted upon base 1 may vary in dimensions, whereby the distance between the respective holes 3 may vary, the base 1 is providedwith means for -receiving. the corresponding screws 3 notwithstanding differing rawings they distances between such screws on different bases 3 'of the switches. To this end the base 1 is providedwith adjustable holding devices 4, located upon its outer or upper surface. The holding devices shown comprise metal pieces provided with threaded holes 4 to receive the screws 3 from the base 3*, and the-holding-pieces 4 are shown held upon base 1. by bolts or screws 5, that pass through corres onding holes in the pieces 4 and through ho es in. base 1 and receive nuts 5, which n uts areslmwn located in recesses6in the under surface of the side portions 1 of base 1. By this means the threaded holes 4* of the holding-pieces 4 maybe adjusted toward and from the center of base 1 to vary the distance between such holes to accord with the distance between the holes 3 of the switch or analogous fitting 3 to be mounted upon base 1 Thus when switches or the like 3 are to be placed upon base 1 the holes 4 of the holding-pieces4 will be adjusted to aline with the holes in the base'of the switch or the like to receive the screws 3, and then, if desired, the nuts 5 may be tightened to retain the holding-pieces 4 firmly in position, and by this means the switches or the like may be centrally mounted. upon base 4 in a conven.

ient and simple manner and firmly held in position.

In order that the holding-pieces 4 may not interfere with the proper fitting of the base 3 upon the base 1 the upper surface of base 1 may be provided with recesses 1, in which the holding-pieces 4 may be located, so that the upper surfaces ofsaid pieces 4 need not project above the top surface of base 1, and thereby the base 3 may fit upon base 1 over the pieces 4 snugly and without interference,

and the holding-pieces 4 may thereby be ad-- justed upon their screws 5 sidewise within the recesses 1 the iequired distance.

\Vhile we have illustrated a snap-switch 3 secured upon base 1 bv the holding-pieces 4, it will be understood that rosettes and analogous electric fittings of roper dimensions and shape may be mounted upon and secured to base 1 by the means shown, the bases being made to accommodate such fittings that mav be usua y upon the market, whereby suc fittings may be conveniently used in connection with the type of conduit shown that has one side open and a removable cover 2. the bases 1 thereby being adapted to a variety of fittings without requiring the latter to be specially formed to fit the bases 1, although t 1e fittings may be made especially adapted to the bases 1.

Having now described our invention, What we claim is- 1. The combination of an electric fitting, with a be. .e upon which said fitting is mounted, said base being provided with adjustable holding devices, that are located between the base and the fitting, and means for connecting the said fitting with said holding devices to hold the fitting upon the base.

2. The combination of an electric switch having a base portion, with abase upon which the switch is mounted, said base being provided with holding-pieces, means for attaching said pieces upon the base so they may be adjusted toward and from the center of the base, and means for securing theswitch upon the holding-pieces.

3. The combination of a base having again on one side and adjustable holding-pieces on the other side, with an electric fitting mounted upon the base, and means for connecting said fitting with said holding-pieces.

4. The combination of a base having a gain on one side, holding-pieces upon the opposite sides of the base, and means for adjustably attachin said pieces upon the base, with an electric fitting mounted upon the base, and means connecting said fitting with said adjustable holding-pieces.

5 A base provided with recesses in one face, adjustable holding-pieces located in said recesses, and bolts or screws passing through said pieces and through holes in the base for adjustably holding said pieces in said recesses.

6. A base provided with a gain in oneside and having recesses in its opposite side on opposite sides of the gain, holding-pieces in t 1e last-named recesses, and means for adjustably retaining said holding-pieces in said recesses. A

7. A base provided with a gain in one side and holes communicating with the gain and with the o posite surface of the base, and recesses in the last-named surface of the base communicatin with said holes.

8. The com ination of a conduit having one side open and a removable cover therefor, a base having a gain receiving said conduit, holes in the base leading from the gain through the o posite face of the base, holdingieces on t e base, a fitting mounted upon the ase, and meansconnecting the fitting with said holding-pieces.
